I'm one of those people who feels the cold. Deeply. I have to fight the urge to turn the thermostat up to 80 degrees or else walk around the house wrapped in a blanket, which impedes progress at every turn. But I found the next best thing.
I learned this little trick from my friend Joan, who learned it from her dear mom. Take an oversized wool pullover sweater, easily found at a thrift shop.
Using good sewing shears, carefully cut it up the middle. The sweater must be wool. The fake acrylic stuff, besides being ugly, won't work because it unravels when you cut it.
Next, fold the cut edges over and whip stitch them up. Easy peasy.
I love big old sweaters, but being short, the pullovers don't work for me. Turning them into cardigans works. Perfect for around the house.
